AudioProcessorValueTreeState raw value pointer thread-safety

[t0m]

Technically, no; they’re not thread safe.

However, unless you’re running on some very unusual hardware, there’s no need to panic.

AudioParameter thread safety

I am looking at the AudioParameterFloat and AudioParameterInt classes in JUCE and I fail to see how they are thread safe. It appears that setValue sets the value and the audio thread gets the value without any sort of fifo or thread safety despite in their base class AudioProcessorParameter it says that getValue and setValue should be “thread aware”. Is it safe to use these classes and set them on the UI thread and get them on the Processing thread as is done in the AudioPlugin Examples?
